FromV the foregoing 'it will beapparent" that v I have devised an Vimiuoved Warning'signal of the character, described ivi-lich is simple vof design @economical of manufacture, and which is adapted to Warn of tampering'with a'parked automobile.`

While. I have shovm my invention in se "f" art that itis not solimited, but is susceptible l 1n `an electric circuit closer,` afreely portable 52 which extendsoutside the casing 35 through an` opening 53 in the side oi thecasing, wherebyl me Vvessel may be levelledfup. The vessel is provided `with a glass cover 54 which prevents f the mercury spilling and the position of the mer- Y Vcuryin the vessel may be observed through the l `eover `Evi` and the'opening 35 inthe casing. Thus the vessel kmay be visually levelled .when the apparatus is set` in a parked automobile. If the vessel isptilted for any reason, as when thecar o various other changes andrmodications, withv out` departing fr'onthe spirit thereof, and I cle-` sire, therefore,y that only such limitations shall be placed thereupon as are" specically set forth in the appended claim. `What I claim is:

casing; a relatively shallow vessel in the casing, means for adjusting the vessel to a level position in the casing, conducting material in thebottom L `L of saidvessel connect-edito one side of said ein. i cuit, a ring conductormounted on the vessel spaced iromthe bottom thereof and connected to the other side of the circuit, and a conducting `fluid in the vesseladapted to bridge the space t between the conducting material in the bottom ofthevessel and the ring conductortoflclose.` f the circuit when the vessel assumes an olf-level` f J `position.
